React hooks for real-time task updates

@trigger.dev/react-hooks gives your React components live access to background tasks. Subscribe to run progress, stream AI output as it generates, or trigger tasks directly from the browser.

Installation

Install the @trigger.dev/react-hooks package in your project:

npm add @trigger.dev/react-hooks

pnpm add @trigger.dev/react-hooks

yarn install @trigger.dev/react-hooks

Authentication

All hooks require authentication with a Public Access Token. Pass the token via the accessToken option:

import { useRealtimeRun } from "@trigger.dev/react-hooks";

export function MyComponent({
  runId,
  publicAccessToken,
}: {
  runId: string;
  publicAccessToken: string;
}) {
  const { run, error } = useRealtimeRun(runId, {
    accessToken: publicAccessToken,
    baseURL: "https://your-trigger-dev-instance.com", // optional, only needed if you are self-hosting Trigger.dev
  });

  // ...
}

Learn more about generating and managing tokens in our authentication guide.

SWR vs Realtime hooks

We offer two “styles” of hooks: SWR and Realtime. SWR hooks use the swr library to fetch data once and cache it. Realtime hooks use Trigger.dev Realtime to subscribe to updates as they happen.

It can be a little confusing which one to use because swr can also be configured to poll for updates. But because of rate-limits and the way the Trigger.dev API works, we recommend using the Realtime hooks for most use cases.
